Synopsis
A cold front moves across the tri-state this evening. High
pressure returns for the middle of the week. A frontal system
will move across the area Thursday night with high pressure
returning on Friday. A series of fronts could move across the
region for the upcoming weekend.

Near term until 6 am this morning
Precipitation out ahead of a cold has come to an end. The cold
front now is moving through the far northwest portion of the
cwa. This front is expected to move across the region through
06z from northwest to southeast, moving through nyc around 03z.

Expect drier and cooler conditions behind the front. Temperatures
will fall into the 50s across the region and become breezy
around day break.

Short term 6 am this morning through 6 pm Wednesday
Deep upper cyclone will pass across northern new england and the
canadian maritimes on Tuesday. A deep NW flow sets up with good
mixing through the day that will lead to gusty winds. Gusts 25 to 30
mph are possible through the day. The NW flow will advect much drier
and more seasonable air into the tri-state as dew points fall
into the upper 30s and lower 40s. High temperatures will be in
the upper 60s to near 70 degrees.

Winds will diminish Tuesday night, but not completely decouple.

High pressure builds towards the region through Tuesday night, so
winds will weaken. Ridging builds aloft with mostly clear skies and
lows in the 40s inland and long island pine barrens to the lower 50s
elsewhere.

Long term Wednesday night through Monday
The long term will feature an amplified upper level pattern with a
deep trough in the west and strong ridging in the southeast.

Multiple waves will move around the periphery of the ridge bringing
a chance of showers for the weekend.

At the surface, high pressure will move offshore Wednesday
night as a warm front advances from the ohio valley with warm
air advection developing. As the front slowly approaches,
showers may develop early Thursday morning. There is a greater
chance for showers Thursday afternoon into Friday morning as low
pressure dives southeast from the great lakes. A rumble of
thunder cannot be ruled out ahead of the approaching cold front.

Dry and warm weather then returns Friday into Friday night as high
pressure builds in.

Another shortwave and approaching cold front may bring showers
Saturday afternoon into Sunday. It is possible the front stalls over
the region into Sunday so have kept chance pops through the weekend.

Temperatures throughout the long term will moderate to above
seasonable normals through the weekend.

Aviation 06z Tuesday through Saturday
A cold front moved south of the region around 05z. High pressure
will build to the west of the area through the forecast period.

Vfr through the TAF period. NW winds will prevail, with winds
around 310 true much of the time. During Tuesday, winds may
slightly back to more of a W to NW directions, to the left of
310 true.

Gusts initially behind the front should become less frequent
and or subside overnight.

Gusts pick up again after 12z, with gusts 20-30 kt. Then gusts
end early this evening, 00z to 01z.

Outlook for 06z Wednesday through Saturday
Tuesday night-Wednesday Vfr.

Thursday Vfr during the day, then MVFR possible at night with a
chance of showers and a slight chance of thunderstorms.

Friday Vfr. Slight chance of showers in the morning.

Saturday Vfr. Slight chance of showers, especially late.

Marine

remain elevated around 5 ft through tonight, and then subside below
5 ft early Tuesday morning. High pressure builds through Tuesday
night, but winds on the waters should not reach SCA levels and ocean
seas will remain below 5 ft.

Sub advisory conditions are expected on all waters through Friday
with a weak pressure gradient. Seas could build to SCA levels Friday
night with easterly flow.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
